REBOL is a powerful software technology (ever thought that you could write a full blown GUI Instant Messenger in
only 7 kb of source code?) designed from the ground up to enable a new era of distributed Internet applications. The technology provides a ubiquitous, lightweight model of distributed computing that operates across all types of computer systems. REBOL is a true distributed computing architecture. Applications and data become distributed across all devices. REBOL is completely device independent, so it does not matter what operating system or hardware is being used. Every system of the Internet becomes an independent resource that can process and communicate information. The REBOL kernel currently runs on more than 40 different operating systems -- everything from large Sun Solaris servers, to Windows and Macintosh PCs, to Linux, BeOS, down to CE handheld devices. And it is here to revolutionize the Internet, by introducing the X Internet (also called as 'XNet') through the REBOL Internet Operating System (IOS).

writing bnf-like parse rules instead of regular expressions is priceless. bit twiddling is difficult. a few bugs on platforms not found other platforms. when saying rebol works on X platforms that is rebol/core the more full featured /view and /command work on progressivly fewer platforms mail-list though highly educational is too much traffic for me to subscribe to, archive site (eScribe) is annoying and stripts headers so it is difficult to respond. documentation, but who doesn't need better docs jumping to new things/products before following thru on old ones (unannounced change of focus) , I geuss you could call that agile and as pointed out repeatedly ... can make programming fun again
